Ramsdale dived to his right to produce a superb fingertip save and stop Salah from scoring a stoppage-time winner.
"I just remember Salah being on his left foot and thinking he's going to cut in and try and put this in the top corner," Ramsdale recalls.
"It was such an emotional, mentally-draining game that you just go into autopilot and you try and find things that you do every day multiple times. Thankfully I was able to call on some of my training and tip it around the post."
It gives Ramsdale back-to-back Castrol Save of the Month awards, after he won March's prize for his dive at the feet of AFC Bournemouth's Dango Ouattara.
"The technical skill between the two is completely different," Ramsdale says. "The March one we went on to win the game, which was special, but the Liverpool one was away, at Anfield, and it was applauded after the game by The Kop.
"These saves are good to have for a compilation video so that when you have a dip in form or confidence, you'll be able to bring out a video of your saves from the previous season to try and remember that it's just a little blip rather than you're actually a bad 'keeper.
"You always want to win individual trophies for actions in games, and it's really good we have this award now for the 'keepers to recognise top-class saves."
The 24-year-old topped a shortlist featuring five other sensational saves by goalkeepers across the month.
